Mux/demux ReDrivers are PCIe 4.0-compliant systems
Two ReDrivers released by Diodes offer four differential channels with 1:2 (demultiplexing) or 2:1 (multiplexing). The PI3EQX16612 (demultiplexing) and PI3EQX16621 (multiplexing) PCIe 4.0-compliant ReDrivers are intended for routing high-speed serial bus signals.
PCIe 4.0 is the preferred serial interface for high-performance IT equipment including desktop and laptop PCs and workstations, and it is also popular for use in embedded systems.
Differential ReDrivers are essential in applications that need to implement longer PCB trace lengths without introducing additional signal latency. The PI3EQX16612 and PI3EQX16621 offer four channels in a single package at speeds of up to 16Gbits per second, per channel. This supports the routing of high-speed serial interfaces across motherboards where longer signal traces are needed to mitigate the effect of more densely populated cards.
They are backwards-compatibility to PCIe 1.0 and offer an adjustable output linear swing, flat gain and equalisation, all of which are configurable through pin strapping. These features allow design optimisation to reduce intersymbol interference across a range of different physical mediums without the need for firmware configuration, says Diodes.
The linear equalisation function operates across speeds from 2.5 to 16Gbits per second, making it suitable for systems using PCIe 1.0, 2.0, 3.0 and 4.0. Each of the four channels is independently configurable, allowing designers to configure each channel based on circuit conditions (e.g. trace length, signal integrity, and component placement).
The PI3EQX16612 and PI3EQX16621 are available now priced.
